Joshua 21:4

And the lot came out for the families of the Kohathites: and the children of Aaron the priest, which were of the Levites, had by lot out of the tribe of Judah, and out of the tribe of Simeon, and out of the tribe of Benjamin, thirteen cities.

Cross-reference

Joshua 21:8-19 lists the 13 towns from Judah, Simeon, Benjamin given to the Kohathites as introduced here.

In Joshua 21:10, the same lot for the Kohathite priests is restated with more detail about the tribes.

In Numbers 35:8, the command to give Levite cities proportionally from each tribe provides the principle behind this distribution.

In 1 Chronicles 6:54-60, the same cities given to Aaron's descendants are listed again, confirming the allocation.

In 1 Chronicles 6:61, the ten cities for the rest of the Kohathites are listed—complementing the priestly allotment here.
